Patients will be checked in the clinic after 1 week to see if additional treatment is needed. If so, re-treatment will be done in a week. If no re-treatment is required, follow-up visits will be scheduled 2, 3, and 6 weeks after treatment, 3 and 6 months after treatment, and every 6 months after that for 2 years to evaluate treatment results. The evaluations will include fluorescein angiograms and other examinations that were done before starting treatment. If abnormal vessels are still present or growing, repeat treatments will be applied following the same procedure.
